If the weight is lost, the dog food is supply in the market.

Explanation:

If the dog lose their weight due to eating of new dog food, it means that the new dog food helps in losing weight of the overweight dogs and then this dog food is recommended to supply in the market due to its effectiveness. On the other hand if the dog did not lose any weight so this food is rejected and another food will be manufactured in order to lose weight.

c. mass = force / accellaration

step-by-step explanation:

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
